Radiating outward from the eye wall
one can see a banded structure within the clouds. These clouds are
called either spiral rain bands (or spiral bands). The image below
is of a hurricane (called cyclone
in the Southern Hemisphere).

There are sometimes gaps in between these bands
where no rain is found. In fact, if one were to travel between the outer
edge of the hurricane to its center, one would
normally progress from light rain to dry back to slightly more intense rain
again over and over with each period of rainfall being more intense and
lasting longer until reaching the eye. Upon exiting the eye and moving
towards the edge of the hurricane, one would see the same events as they did
going in, but in opposite order.
